Hi. You did not submit the sample that the question refers to, nor did you submit your answer. This makes it impossible for this question to be answered. However, I will try to help you as best I can.
Your question asks you to compare your answer with a model answer. You don't show the context these two answers are related to, so you should look for that context in your paper. It is likely that these answers are related to the previous question.
To make the comparison you should note which elements these questions have similar or equal and how they complement each other. The more similar, the more complementary the two answers are. If the two answers do not complement each other, nor do they have any similar elements, it means that they are completely different.
